Meebo is ramping up its Community instant messaging (IM) program and bringing real-time messaging to your favourite social networks. Users of the popular high school site, myYearbook, can now chat with friends on this web-based instant message application, across multiple networks.

Most recently Meebo Community IM launched on Flixster, and now there are 25 partners using the instant messaging tool on their own sites. myYearbook is by far the largest of those partnering sites, with over nine million unique visitors monthly.

Meebo looks and functions similar to Facebook’s IM where users can view friends online, have multiple browser chats and receive real-time notifications of status updates. The application offers social networks a way to introduce chat bars without having to develop one on their own.

The new application offers publishers a way to increase user engagement, while simultaneously giving them another source of revenue: an interactive ad platform that’s due out next month.

While myYearbook may look like the pages of a Tiger Beat Magazine, it has already been greatly successful in raising thousands of dollars for charitable causes, drawing high volume traffic to its site and growing a dedicated base of users.
